To all whom it may Concern Be it known that l, HanrLnY O. BAKER, avr citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain newand Y to construct the main vburner to close the y lower end of the generator' casing, said burner being provided with mixing tubes Y and circuitous air passages leading to the mixing tubes whereby the air in its passage through said circuitous passages will lbe heat ed prior' yto its admixture with the hydroe` carbon sprayed into themixing tubes.

vAnother object of the invention is to preheat the air prior to its'admixture with'the gases. and its passage through the burner and .generator coils which eliminates the chilling' of the burner and boiler tubes usual in lall standard and Vother known generators or boilers.

A further object of the invention is to prevent the'rushing of cold air directly intoV the main burnerl to Veliminateor mulilethe usual blowing or whistling of the burner when starting up or speeding against; the wind. p

A further object of the invention is to prevent the gases from 'lighting back to the burner tips when the main burner is shut od, by they air being drawn through` ciri cuitous air passages of the main burner, thus eliminating the impression of the Ordinary Observer' that the 'burner is on fire.

A further object' of the invention is to construct the main burner in such a man# ner and intimately associate With itthe fuel vaporizing means that the vflame or fire of* the main burner will not Over-heatthe va'- .porizing means, thus preventing the for? ina-tion of a heavy tarry substance or other foreign matter therein. Y

A. still further object of the invention is to' provide a vtwo compartment main burner, each having a mixing tube and a circuitous air passage communicating 'with theinixing thereof@` spcification of Letters Patent. j 'PatentedDee 2, 1919.

tube whereby' 'the air willbe pre-.heated prior to its admlXture with the hydrocarbon 'and ments of the burner.

vA still further object of thel inventionis to itspassage into the respective compartf.

the accompanying drawings, and will now The bottom part 1 is provided at its front with an inwardly extending recess 5 or the f accommodation of a primary or pilot burner 6, shown in Fig. 1. partit-ion extends diainetrically of thebottom part and is provided throughout its length with a central air passage 7 which establishes communication with the atmosphere at the back of the burner and the recess 5 andL the primary burner positioned therein. 'The primary burner-fis constructed to exactly iill the recess 5 and its only means of air supply through the passage 7 communicating with the interior thereof and the atmosphere.

The cover plate is provided diametrically with a rib Sito rest upon the diametrical f partition of the bottom part, said partition andrib serving to divide, the burner into two compartments each entirely separated from the other. The cover plate is also provided with spaced grooves which extend in parallel relation from front to baclrof the burner. 10 indicates gas emitting slits which extend from one groove 9 to the next adjacent one. Tf desirable these slits may be? dispensed with and perforations used in lieu thereof.

Partitions 11 extend in opposite directions within the burner from the primary burner compartment to the sides of the burner to provide air compartments 12. Each compartment of' the main burner is provided with a pair of spaced air tubes 13 which es-` tablish communicationi between the air chambers 12 and the atmosphere in rear of theburner. An ordinary mixing tube 1l extends through each partition llrinto Vthe center of each main burner compartment and as clearly shown in Fig'. 9 is positioned between the air tubes 13.- The front wall of each air chamber 12 is provided with an opening 15 in axial alinement with the mixing tubes 14, through which is adapted'to project needle valves 16. From this construction it will be apparent that all air will be drawn through the hot tubes 13 and thorougly heated prior to its admixture with the hydrocarbon which is shot into the mixing tubes from the needle valves 16. This preheating of the air prior toits admixture with the hydrocarbon will serve to make the burner more effective in its operation inasmuch as the burner and generator coils po-V sitioned immediately above will be prevented from becoming chilled as is the case with most generators Yor boilers. This elimination of the rushing of cold air into thek main burner Vwill prevent the roaring or whistlingoi' the main fire which is so well V known and annoying ingenerators of standard and well lriiown construction..l It will also be apparent that the air vsupplied through the passage 7 to the primary or pilot burner will be pre-heated by its pas- 1siage through the mainburner beneath the The primary or pilot burner is fed with hydrocarbon through the medium of av -needle valve identical inconstruction with inner and outer walls 18 and 19 separated by an asbestos or heat resistingpacking 20,

` inner wall 18 projecting upwardly to provide a flange 21 for insertion within the lower endy of the generator casing 22. This y housing is adapted to be detachably connected in any suitable manner Vto tliegenerator casing. j j Y AThe housing 17 is vprovidfal at its front with 4an auxiliary aousing having` va cover plate 2i detachably' connected thereto by thumb nuts 25. This cover plate is provided with openings 26 whereby access may be readily had to the needle "valves 16. ,The

cover plate is also provided, witha hand opening anda closure door 27 therefor. By opening the door `27"free and ready access may be hadto the burner. Y

rShe, mainburner is constructedin a particular manner to cooperate with the fuel vapo-rising` means which is intimately associated with it as clearly shownin Figs. l1,

11 and 12. This vaporizing means consists of a plurality of fuel pipes connected in a mannerto form a circuitous fuel passage as This indicated by the arrows in Fig. 11. fuel vaporizer is adapted vt0 be so constructed and associated with the main burner that it will burn v rions Lgrades and qualities of hydrocarbon without necessitating any change or adjustment iii its structure.k Each of the spaced 'parallel `pipes forming the fuel vaporizer are of vsuch diameter that when positioned within the grooves 9 ofthe main burner they 'will rest in a plane just below the ilanieof the main burner, thus by virtue oftheir being out ofthe flame preventing over-heating which causes the for-V mation of a heavy tarry substance or other iio foreign deposits Within the ,vaporizer fuel pi es.V

y particular reference stiucted to'vaporize ii'ar'ious kindsfof hydrocarbon fuels such for instance asf kerosene and gasolene Without the necessity of any change in the structurel If it is desired to use `gasolene as a fuel, it -is fed under` pres- .ire through the valved pipe 28, which Will close the check valvel 32 in the pipe 4l, and then through needle valve 29, whichv is controlled by the fluid or steam pressure regulator 30, pipe 31, T coupling 33 in opposite' directions through the .Y pipes 34 and 35, which latter' passes over the pilot burner, and connects with the pipes 36 that are attached to the needle spray valves 16.

Should it be desired to use kerosene or heavy distillate, the valve in the gasolene feed pipe is closed andthe valve in the kerosene feed pipe 87 opeiied,'ivhereby it ivill be A apparent that the kerosene ivill floiv in op-'f posite directions through the pipes 38, 39A

and a0, to the pipe atl through the check valve 32 to the pipe line 28 and thence Y through the needle valve 29, from Where the fuel takes the saine course as previously de-V scribed in connection with the feedingof gasolene or lighter hydrocarbon.

i2 is a fuel feed pipe leading to the Apilot burner and is provided with a suitable con-y trolling valve a3. This fuel feeding and va# porizing means is of a particular Vconstruetion adapted for use in connection with this particular construction of main burner and is specifically covered in a separate application, Serial No. 222,153, hereinbefore referredto.
